I initially didn’t think much about it, until I discovered the facebook heart likes-
Finally I asked why he was so intent, on committing fraud to help, this woman-
Then he confessed, they were more than friends, that they had been intimate-
He said they didn’t date, then I found out they did, and finally I discovered the vacation they took together.
feel disrespected, lied to, and embarrassed
He brought all this to me, seeking my opinion-
I feel there was definitely a lot more to this
